Standover Height Range: 27.5-28.0 inches
...This is the distance from the top of the top tube (measured at its midpoint between the seat tube and head tube) to the ground...
Virtual Top Tube Range: 23.9-24.3 inches
This is not a measurement of the actual top tube itself. Rather, this corresponds to the mountain bike industry standard of measuring an imaginary line drawn parallel to the ground along the length of the top tube from the midpoint at the seat tube to the midpoint at the head tube. This is also known as an "effective top tube." No single piece of frame geometry has a greater impact on comfort than your top tube. If you plan on paying attention to one measurement and one measurement only, make it this one.
Stem Length: 7.7-10.1 centimeters
This measurement indicates your ideal stem length. It takes into account that your stem will be flipped to its flatter angle (e.g. 80°, aka -6°, for Easton).
BB-Saddle Position: 60.6-66.6 centimeters
This measurement is along the seat tube, from the center of the bottom bracket spindle to the top of the saddle. It is an ideal starting point for saddle height. Given the varying differences of cleat and pedal heights, and given the varying differences in the thickness of saddles, the BB-Saddle position has a broad range of 2cm.
Saddle-Handlebar: 53.1-54.9 centimeters
This measurement ties together your choice of stem length with the fore/aft position of your saddle. It is measured from the nose of the saddle to the near edge of your handlebar. Keeping within this range will assure that you don't accidentally push the weight balance of your body either too far forward or backward.
